First Monthly LRAD Public Safety Siren Test
Saturday, August 3 - Noon
Various locations around Mill Valley
You may hear a new sound this Saturday at noon in Mill Valley - the new and more powerful emergency sirens, known as "LRADs" - Long Range Acoustic Devices. They project both siren and voice recordings to alert and inform you during a large-scale disaster. These new sirens are the first land-based LRAD system in Marin County.
